Geometry

In this guide, you’ll learn how to calculate the moment of inertia of an uncracked reinforced concrete section and how 2 materials work together in a cross-section.

In this post, we’ll show the formulas of the polar section modulus for 8 different shapes and sections.

In this post, we’ll show the formulas of the polar moment of inertia for 10 different shapes and sections.

We’ll explain what a roof joist is, how it works, how structural engineers design it and what the difference to ceiling joists is.

In this guide, we’ll walk you through how to calculate the Centroid of I Sections of beams and columns. Everything is explained with practical examples.
